Other mistake: When Robocop jumps on top of RoboCain, there's a moment where RoboCain backs up, and you can see a burning car in the background. The background footage is in a weird, stuttering frame rate that's unintentional. (Likely the result of the shot needing to be re-timed by doubling or tripling frames for the stop-motion animation in the foreground.)
Suggested correction: You need to be clearer. Throughout the scene, all the fire effects appear to be shot live action. What exactly is the mistake you're seeing?
The mistake is poorly worded, but correct. When Robocop jumps on top of RoboCain, there's a moment where RoboCain backs up, and you can see a burning car in the background.
